Reciprocity has a lot of meanings. Below are some very common meanings. For me I simply say it this way; ” Give and Take”, or “Do unto others what you want others do unto you” , or mutual action, or “what good you make to others, it will simply return unto you”.(Sistah Twinks, your wish is my command)

The ethic of reciprocity or the Golden Rule is a fundamental moral principle and meme which simply means “treat others as you would like to be treated.” It is arguably the most essential basis for the modern concept of human rights. Principal philosophers and religious figures have stated it in different ways.

The Principle of Understanding

Ethical teaching interprets the Golden Rule as mutual respect for one’s neighbour (rather than as a deontological or consequentialist rule.) Many people have criticized the golden rule; George Bernard Shaw once said that “The golden rule is that there are no golden rules”. Shaw also criticized the golden rule, “Do not do unto others as you would expect they should do unto you. Their tastes may not be the same.” (Maxims for Revolutionists). “The golden rule is a good standard which is further improved by doing unto others, wherever possible, as they want to be done by.” Karl Popper (The Open Society and Its Enemies, Vol. 2) A key element of the ethic of reciprocity is that a person attempting to live by this rule treats all people, not just members of his or her in-group, with consideration.
